14 Claims.

This invention relates to weatherstrips, particularly metal weatherstrips for windows equipped with sliding sashes. It has for its principal objects to provide a simple and economical jamb Weatherstrip which can be quickly and easily applied to the window; which will cooperate with the inside and outside stops of the window frame to form the slideways for the upper and lower sashes; which will prevent rattling of the sashes in the frame; which will automatically accommodate itself to shrinking and swelling of the sashes and frame and, at the same time, maintain a sliding weatherproof joint therebetween; and which will permit the sashes to be mounted in and dismounted from the frame without removing the Weatherstrip. The invention consists in the Weatherstrip and in the construction, combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification and wherein like symbols refer to like parts wherever they occur:

Fig, 1 is a horizontal section through one side of a window provided with a metal Weatherstrip embodying my invention,

Fig. 2 is a similar section, showing the position assumed by said Weatherstrip during the operation of mounting the top sash in the window frame,

Fig. 3 is a similar section showing the position taken by said Weatherstrip while the bottom sash is being mounted in said frame,

Fig. 4 is a perspective view of a portion of the intermediate section of the Weatherstrip; and

Fig. 5 is a perspective view of a portion of one of the side sections of said Weatherstrip.

In the accompanying drawing, my invention is shown embodied in a window construction comprising a frame including a jamb l, a finish or inside stop 2, a blind or outside stop 3 and vertically slidable top and bottom sashes, G and 5, respectively. The joints or spaces between the opposed faces of the jamb l and top and bottom sashes are rendered weatherproof and dustproof by means of a sectional Weatherstrip A that is mounted on the sash opposing face of said jamb and extends continuously thereof between the sill and head members (not shown) of the window frame between the inner and outer stops thereof. The sectional Weatherstrip A comprises a relatively rigid intermediate floating section B, and relatively flexible or resilient side sections C rigidly secured to the jamb I and adapted to support said intermediate section for bodily movement towards and away from the inside face of said jamb.

The intermediate section B of the jamb Weatherstrip A comprises a strip of metal or other suitable material that is bent or otherwise shaped to provide on the sash opposing face thereof a channel-shaped longitudinal medial rib 6, U-shaped longitudinal side marginal ribs 1 and a U-shaped longitudinal groove 8 between said medial rib and each of said side marginal ribs. The outer side wall of each side marginal rib l of the intermediate section B defines one side edge thereof and has a free marginal portion that is disposed inwardly of the adjacent longitudinal groove 8 and is bent inwardly and thence outwardly to form a substantially V-shaped longitudinal groove 9 in said side edge back of the rib I and the groove 8.

Each of the side sections C of the jamb Weatherstrip A comprises an elongated strip of metal or other suitable material bent along longitudinal lines to form a base portion H), a resilient flange II along one side margin of said base portion and a hollow longitudinal anchoring rib l2 along the other side margin of said base portion. As shown in the drawing, the resilient flange ll of each side section C is normally disposed at an oblique angle to the base portion l0 thereof and terminates at its free margin in a hollow bead I3. The resilent flange ll of each side section C has spaced parallel shallow longitudinal hollow ribs 14 therein adapted to stiffen said flange longitudinally and to prevent distortion thereof due to strains set up therein during the operation of forming the rib l2 and bead 13 of said section.

The sectional Weatherstrip A is attached to the jamb I by engaging the beaded free marginal edges [3 of the resilient flanges ll of the two side sections B with the V-shaped grooves 9 in the side edges of the intermediate section C and by forcibly inserting the compressible hollow side marginal ribs l2 of said side sections in vertical grooves 15 provided therefor in the sash opposing face of said jamb. In this attached position of the Weatherstrip, the resilient flanges ll of the side sections C thereof are inclined outwardly away from the jamb I and the intermediate section B is supported between said side strips by the engagement of the free beaded margins [3 of said resilient flanges with the V-shaped grooves 9 in the side edges of said intermediate section.

The medial rib 6 of the intermediate section B is disposed between the top and bottom sashes and operates as a parting bead or strip therefor.

The jamb opposing face of each of the top and bottom sashes has a vertical U-shaped groove [6 therein adapted to receive the adjacent U-shaped side marginal rib l of the intermediate section B. The jamb opposing face of each sash is also provided between the groove l6 therein and the parting bead opposing face thereof with a U- shaped vertical rib ll that slidably engages the adjacent U-shaped groove 8 in the intermediate section. The ribs ll of the sashes bear against the bottoms of the grooves 8 provided therefor in the intermediate section B of the weatherstrip and thus press said section inwardly in the direction of the jamb l; and this inward pressure is transmitted through the inner side walls of the V-shaped grooves 9 in the side edges of said intermediate section to the resilient flanges H of the two side sections of said Weatherstrip, thereby placing said flanges under suflicient tension to maintain the beaded free margins l3 thereof in contact with said inner side walls of said V-shaped grooves and thus preventing passage of air or dust through the floating joints between said intermediate and side sections. As shown in the drawing, a clearance space is normally provided between the side marginal ribs I of the intermediate section of the Weatherstrip and the grooves l6 provided therefor in the sashes. The ribs [1 of said sashes are normally spaced from the sides of the grooves 8 provided therefor in said intermediate section but have substantially line contact with the bottoms of said grooves to thereby prevent passage of air or dust between the sashes and intermediate section.

By the arrangement described, the two side sections of the Weatherstrip are rigidly secured along their remote side margins to the jamb I without the use of nails or other separate fasteners, while the intermediate section of said Weatherstrip is resiliently supported by said side sections for movement with sashes towards and away from the jamb. The resilient sealing flanges of the two side sections are held under tension by the sashes and thus serve to maintain weatherproof connections between the side and intermediate sections and between the intermediate section and the sashes and to prevent rattling of the latter in the frame. The resilient supporting flanges of the side sections permit movement of the intermediate section with the sashes towards and away from the jamb to accommodate shrinking and swelling of the sashes and to insure sliding movement thereof in the frame. The medial longitudinal rib of the intermediate section serves as a parting strip or bead for the two sashes; and the clearance spaces between the jamb and the intermediate section of the combined sash guide and Weatherstrip permit said section to move inwardly far enough to permit the sashes to be inserted in and removed from the frame without dismounting said Weatherstrip.

As shown in Fig. 2, when the top sash is inserted in the frame, said sash forces the intermediate section of the Weatherstrip towards the jamb far enough to provide the necessary clearance for the sash. After the top sash is in proper position, the pressure of the resilient side flanges of the side sections of the Weatherstrip on the intermediate section thereof causes the rib and groove at the outer margin of said intermediate section to snap into engagement with the groove and rib provided therefor in said sash. As shown in Fig. 3, when the bottom sash is inserted in the frame, the engagement of said sash with the inner side rib along the inner side margin of the intermediate section of the weatherstrip forces said margin in the direction of the jamb to thus provide sufficient clearance for said sash. When the bottom sash is in proper position, the outward pressure of the side sections on the intermediate section causes the rib and groove along the inner margin of said intermediate section to snap into engagement with the groove and rib provided therefor in the sash. When the intermediate section of the Weatherstrip is forced inwardly, during the operation of mounting and dismounting the sashes, the hollow channel-shaped rib of the intermediate section of said Weatherstrip straddles thevertical rib on the sash opposing face of the jamb between the clearance recesses on opposite sides of said rib, thereby preventing excessive crosswise movement of said intermediate section relative to said side sections. In the normal, sash guiding and supporting position of the intermediate section, such crosswise movement of the intermediate section and sashes is yieldably resisted by the side sections due to the reverse inclination of the inner walls of the outwardly opening grooves along the opposite side edges of said intermediate section. The engagement of the free margins of the sealing flanges of the two side sections with the V- shaped grooves in the side edges of the intermediate section form floating hinge connections between the side and intermediate sections that permit limited movement of the intermediate section while maintaining weatherproof joints between said sections during such movement.

Obviously, the hereinbefore described construction admits of considerable modification without departing from the invention. Therefore, I do not wish to be limited to the specific construction and arrangement shown.
